Riot Games Rate Limits

Riot enforces app-level rate limits per region and per API key, plus method-level limits on individual endpoints. Limits are applied across both the user's personal/production app and the underlying service; either layer can return 429. Limits scale with key tier (development/personal vs production), with production-key limits expandable for developers in good standing.

Riot Games Rate Limits is the machine-readable rate-limit profile for Riot Games on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, measuring requests_per_second, requests_per_2_minutes, requests_per_10_seconds, requests_per_10_minutes, and varies.

Limit state is signalled in the retryAfter and rateLimitType response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Riot Games, League of Legends, VALORANT, and Rate Limiting.

see endpoint reference
Individual endpoints carry their own per-method limits in addition to the app-level caps; method limits surface as 429 with X-Rate-Limit-Type when triggered at the edge.

Policies

Per-Region Enforcement
All rate limits are enforced per regional shard (e.g. NA1, EUW1, KR). A single key can run against multiple regions but each region carries its own counter.
Retry-After Compliance
Clients must honor the Retry-After header on 429 responses and pause until the indicated time before retrying.
Rate Limit Type Header
When the 429 originates at the API edge, X-Rate-Limit-Type identifies whether the breach was at the application or method layer. The header is not guaranteed for 429s surfaced by the underlying service.
Production Approval
Production-key issuance and any subsequent rate-limit raise requires Developer Relations review of a working prototype and adherence to Riot's developer policies.
